Pros & Cons
Campaign Monitor
Pros
- The drag-and-drop editor and mobile-ready templates let non-technical users build polished emails quickly.
- Agencies get multi-brand and white-label client account features.
- Essentials includes unlimited sends at a moderate starting price.
- The integration directory lists more than 100 connections, including Salesforce, HubSpot, Shopify and Zapier, plus a REST API.
Cons
- The price jumps sharply from Essentials to Premier, and reviewers call the tier structure confusing.
- Automation lacks advanced branching, lead scoring and cross-channel logic.
- There is no live chat on any plan, and phone support is limited to Premier.
- Reviewers report that the Salesforce connector is unreliable and the Shopify sync is shallow.
- There is no permanent free plan, only a 30-day trial.
Klaviyo
Pros
- Deep native integration with Shopify and other stores lets marketers segment on real purchase and browsing data.
- A free plan with 250 profiles and a 20 USD entry plan make it cheap to start.
- Since July 2026, SMS uses dollar-based plans with over 70 tiers, so gaps between plans are smaller and larger plans get lower per-message rates.
- A broad product suite covering reviews, helpdesk, personalization and AI agents can replace several separate tools.
Cons
- Billing by active profiles and uneven tier steps cause cost jumps, for example from 150 USD at 10,000 profiles to 350 USD at 15,000 on the Email plan.
- Many features, such as Reviews, Helpdesk, Personalization and Composer, are separately priced add-ons that raise the total bill.
- Free accounts get email support only for the first 60 days, and reviewers on G2 and Trustpilot report slow or hard-to-reach support.
- New users report a learning curve with segments, event triggers and flow logic.
